Presentation
How do you maintain the stability and security of a large-scale Kubernetes environment within an enterprise infrastructure? Containerisation underpins software agility and continuous deployment. As hybrid environments become more complex, you must ensure uninterrupted availability while maintaining precise control over access and the isolation of critical resources.
This course addresses the challenges of operating clusters that host business-critical applications. You will explore advanced OpenShift Container Platform 4.21 features to manage production environments to enterprise standards. The course develops your expertise in multi-tenancy, network traffic protection and add-on management through Operators.
You will be able to manage clusters securely, whether they host services from internal teams or external providers. You will learn to enable developer self-service while maintaining rigorous governance and monitoring. The course also prepares you for the official certification exam for Red Hat Certified OpenShift Administrator (EX280), providing formal recognition of your expertise (see the Certification tab for details).
Objectives
By the end of this Red Hat administration course, you will be able to:
- Deploy packaged applications using manifests, templates, Kustomize and Helm.
- Configure authentication and authorisation to secure user and application access.
- Protect network traffic through security policies and controlled service exposure.
- Administer and manage application life cycles using Kubernetes resources.
- Enable self-service so developers can manage their own projects.
- Manage critical cluster and Operator updates to keep the system sustainable.
- Prepare for the Red Hat Certified OpenShift Administrator (EX280) exam.
